Answer:
Step-by-step explanation:
1) Let width = x
One side of the rectangle is covered by river. So only, 3 sides to be covered.
length = 100 - ( x + x) = 100 - 2x
Area of rectangle = length *width
= (100 - 2x)*x
f(x) = 100x - 2x^{2}

Answer:
The weight of Rachel is less than 40 Pounds.
The weight of Stephanie is less than 120 Pounds
Step-by-step explanation:
Sum of both both their weights is less than 160 pounds.
Let the weight of Rachel = k Pounds
⇒The weight of Stephanie = (3k) pounds
Now, according to the question:
k + 3k < 160
or, 4k < 160
⇒ k < 160/ 4 = 40
or, k < 40
⇒ The weight of Rachel is less than 40 Pounds.
and The weight of Stephanie is less than (3 k = 3 x 40) 120 Pounds
Pounds, or kilograms depending on region.
3x^2 - 2x - 1
x + 2 Γ 3x^3 + 4x^2 - 5x - 2
3x^3 + 6x^2
-2x^2 - 5x - 2
-2x^2 - 4x
-x - 2
-x - 2
0
Therefore, solution is 3x^2 - 2x - 1
Answer:
1
Step-by-step explanation:
a+1=1
a=1-1
a=0
b^a which means:
b^0
whenever power is 0 answer is always one
so value of b^a is 1
